James Webb space telescope: Deep insights into a "Jupiter without a star"
Because it's traveling without an interfering star, the James Webb Space Telescope was able to study a solitary, planet-like celestial body in particular detail.
Webb telescope spots curious objects that aren't stars, or planets
Astronomers used the powerful James Webb Space Telescope to sleuth out some of these objects, called brown dwarfs, in a vibrant star-forming region of our galaxy called the Flame Nebula. Brown dwarfs are too small to trigger the nuclear engines in stars, but are more massive than most planets. They are unbound, free-flying objects in the universe.
